General-purpose

output port

Connect a 75kHz crystal

oscillator for the reference

frequency to these pins.

Serial I / O port.

Use this pin to set the

divide ratio and divide

method, as well as transfer

data to and from the

controller to control the

general-purpose counter and

general-purpose I / O port.

This is an open-collector

output port.

Use this port to output

control signals.

This pin controls the DC / DC

converter.

The VDD power supply from

the DC / DC converter is

applied to this pin.

The device is placed in

standby mode when a “L” is

input.

The device is in active state

when a “H” is input.

Use this pin for IF signal

input on the FM side.

Use this pin as the reference

of the IF signal.

Use this pin for IF signal

input on the AM side.
